HPC Mobilair M27/M31

As with every KAESER rotary screw compressor, a premium quality airend featuring world-renowned SIGMA PROFILE rotors lies at the heart of all M 27 and M 31 models and delivers more compressed air for less energy. The standard working pressure for these machines is 7 bar; 10, 12 and 14 bar versions are also available.

Compact powerhouse

Both models are more than just reliable air compressors. With the optionally available 6.5 kVA generator, they become construction site powerhouses providing a dependable supply of compressed air and / or electricity.

Compressed air quality

Aftercoolers and condensate separators are available for applications requiring cool, dry compressed air. The M 27 and M 31 compressors without air treatment systems feature KAESER’s patented Anti-Frost Control as standard. Together with an optional tool lubricator, the Anti-Frost Control prevents compressed air tools from freezing up, even in cold ambient temperatures.

Useful extras

A multitude of carefully considered options makes these portable compressors even more versatile: for example, a hose reel with twenty metres of lightweight hose, a toolbox for convenient storage and a closed floor pan. A version designed for use in refineries is available, which includes a spark arrestor and an engine shut-off valve. A check valve is provided for sandblasting applications.

Cool, dry compressed air

The compressed air aftercooler cools the compressed air to 7°C above ambient. Because the aftercooler is installed at an angle the condensate is able to drain away easily. This environmentally-friendly design prevents problems caused by freezing in winter and the condensate is evaporated using the hot exhaust gases from the engine.

Impressive performance

The PE fuel tank fits perfectly into the available space and holds enough diesel fuel for extended operation without the need for refuelling. A cleaning opening is located in the floor pan which ensures that the machine can be kept clean and running at optimum performance.

Service-friendly

The wide-opening enclosure provides excellent component access, which makes service work a breeze thereby ensuring maximum compressed air availability
